Fertilizing method and fertilizing device for fruit-bearing forests in mountainous regions

Abstract

The invention discloses a fertilizing method and a fertilizing device for fruit-bearing forests in mountainous regions. The fertilizing method includes the steps of a, computing fertilizer component ratios and consumption according to varieties and growth periods of fruit trees and preparing fertilizers; b, designing different sizes of fertilizer hoppers according to fertilizing amount for the fruit trees; c, selecting multiple fertilizing points according to the total fertilization amount of every tree; d, perforating by a steel chisel or drilling rod, and embedding one or more fertilizer hoppers into holes; e, filling the fertilizer hoppers with the fertilizers. Every fertilizer hopper comprises a hopper body and a hopper cover which are both made of anticorrosive materials such as metal and plastics, the diameter of the hopper body ranges from 10 mm to 200 mm, the height of the hopper body ranges from 50 mm to 500 mm, the lower end of the hopper body is round or conical, a plurality of leaking holes 1-10 mm in diameter are formed in the sidewall and the bottom of the hopper body, and the hopper cover is bright in color.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method and device for fertilizing mountain fruit forests. Background technique [0002] Economic trees such as pecans, Chinese torreya, fruit trees, and tea trees are the main source of income for local forest farmers. These trees are generally planted on mountainous terrain. Some plots have steep slopes. At present, fertilization mainly adopts the mode of throwing on the ground below the tree crown. Although this fertilization method is simple, the fertilizer utilization rate is not high, generally less than 30%. Because the fertilizer sprinkled on the ground will be decomposed and volatilized on sunny days (especially when there is direct sunlight), and will be washed away by the water flow when it rains, and the unused fertilizer will pollute the water source under the mountain. Another method of fertilization is to select a fertilization point under the tree canopy ...

AI Technical Summary

Problems solved by technology

Although this method reduces the loss and volatilization of chemical fertilizers, it is easy to damage tree roots, and it is labor-intensive, time-consuming, labor-intensive, and inefficient. It is difficult to precisely control the depth of digging and the amount of fertilizer applied, and it is not suitable for the development of large-scale and efficient agriculture. direction

[0003] In addition to the above-mentioned traditional methods, at present, there is no fertilization machine suitable for mountainous areas at home and abroad, especially for mountainous areas with a slope of more than 30°, and it is still difficult to develop a practical fertilization machine applicable to mountainous areas on the basis of existing technologies. accomplish

If pipe drip irrigation is used for fertilization, there are also problems such as large investment in initial installation, high management costs in the later stage, and insufficient water supply in mountainous areas, so it is difficult to popularize
